    Change from using @In to Component.getInstance()

    scott duke Novice

      Maybe there is a better way of what I want to do, if so, then please tell me.


      I want to create a controller for posting various imported data. Since I am going to post either one or multiple files, I did not want to use the @In annotation, but rather Component.getInstance(). I created a MasterBean stateless class and a SlaveBean stateless class for testing. When I ran the classes using @In, everything works fine. When I switched to use Component.getInstance(), I receive the following error:
